Giulio Avanzini (M.Sc in Aeronautical Engineering and Ph.D. in Theoretical and Applied Mechanics) is Professor in Flight Mechanics at Sapienza Università di Roma, teaching courses in Flight Dynamics and Flight Mechanics of Rotary Wing Aircraft. He served as full professor at Università del Salento, teaching courses of Flight Mechanics, Atmospheric and Space Flight Dynamics and Aircraft Design. He was research staff at the Italian Ship Model Basin in 1997, then assistant professor at Politecnico di Torino from 1998 to 2011, teaching atmospheric and space flight mechanics. He was visiting professor at the University of Glasgow and University of Illinois at Urbana-Champaign, teaching classes in spaceflight dynamics and dynamics of flexible aircraft. His research interests include nonlinear methods for the analysis of aircraft and spacecraft dynamics; direct and inverse simulation of aircraft and rotorcraft motion; autonomous flight; spacecraft attitude dynamics and control; satellite formation flying (with a focus on tethered formations); fundamental problems in Astrodynamics; autonomous underwater vehicles; performance and sizing of electric and hybrid-electric aircraft and rotorcraft.
